ABSTRACT
Bibliographies, discographies, and filmographies provide lists of sources that are typically restricted to a specific topic, geographic region, or field. Bibliographic guides of this kind, especially when annotated, can help researchers identify the broad body of literature connected to a research topic. Annotated bibliographies have the added benefit of helping users evaluate the usefulness of sources for their project. Bibliographic guides are produced in book-length form, but significant guides to music by region or topic are found also in articles published in books and journals, and now on the Web.
